Abstract
A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.
Claims13
A tool for cutting an axle shaft, said tool comprising:
- (a) a scissor arms assembly having a first arm having proximal and distal ends, having a second arm having proximal and distal ends, and having a hinge interconnecting said arms' proximal ends;
- (b) a cylindrical sleeve having a hollow bore and having a wall, said sleeve being fixedly attached to or formed wholly with the first arm's distal end, wherein the hollow bore is sized for receiving the axle shaft;
- (c) a threaded channel extending through the wall;
- (d) a set screw received within the threaded channel, wherein upon a receipt of the axle shaft within the hollow bore and upon turning the set screw, the set screw holds the axle shaft against the wall;
- and
- (e) a cutting wheel assembly comprising a cutting wheel, the cutting wheel assembly operatively mounted at the second arm's distal end and movable along with said second arm's distal end about said hinge toward an axis extending through both ends of said hollow bore such that said cutting wheel is movable through said axis for cutting the axle shaft held in said cylindrical sleeve.

A tool for cutting an axle shaft, said tool comprising:
- (a) a scissor arms assembly having a first arm having proximal and distal ends, having a second arm having proximal and distal ends, and having a hinge interconnecting said arms' proximal ends;
- (b) a “C” clamp having a pair of walls defining a throat, said “C” clamp being fixedly attached to or formed wholly with the first arm's distal end, wherein the “C” clamp is sized for receiving the axle shaft;
- (c) a shaft aligning concavity within one of walls;
- (d) a threaded channel extending through the other wall among the throat's pair of walls;
- (e) a set screw received within the threaded channel;
- (f) a cutting wheel assembly comprising a cutting wheel within a cutting plane, the cutting wheel assembly further comprising a drive axle and rotary bearing combination, wherein the drive axle has a drill chuck attachment end extending oppositely from the cutting wheel, wherein the cutting wheel assembly is operatively mounted at the second arm's distal end and, wherein, upon a receipt of the axle shaft within the throat and upon turning the set screw, the set screw holds the axle shaft against the shaft aligning concavity;
- (g) a hollow bore extending through the second arm's distal end, said bore receiving the drive axle and rotary bearing combination;
- (h) a shaft insertion stop fixedly attached to the “C” clamp;
- and
- (i) a cutting channel bounded by the “C” clamp and by the shaft insertion stop, wherein the cutting plane extends through the cutting channel.
